Mitsubishi Evolution Boost Control Solenoid - COBB - 3-Port - `08-`12. This COBB 3-port electronic boost control solenoid delivers precise, repeatable boost management for 2008–2012 Evo X and 2009–2012 Lancer Ralliart.

Upgrading to a 3-port solenoid enhances boost targeting, reduces overshoot, and helps the turbo reach and hold requested boost more consistently when properly calibrated. Engineered for reliable operation and fine control, it integrates with the factory ECU strategy and supports both stock and upgraded turbo setups. A proper tune (COBB Accessport or professional calibration) is required after installation to realize the benefits and ensure safe operation.
